Theraband Coupling Solution - Parametric by Shanjaq

Last crawled date: 3 years, 4 months ago

This should work better than zip-ties for binding Theraband elastic tubes to polypropylene rope/cord. Calibrated for the "black" tubes, OpenSCAD source files included if you want to adjust the parameters for the "silver" or other-sized tubes (be sure to copy your parameters to all 3 .scad files before printing the complete set!)
wall thickness: 1.6mm
top/bottom thickness: 1.2mm
plate adhesion: brim
I just used a Bowline Hitch for the loop connections, also recommend wetting the tube with rubbing alcohol before inserting the sphere on its cord held in place by a knot at the bulb-end.
